Summary and analysis by Subvolts editorial, AI-assisted.
On the No Priors podcast, hosts Sarah Guo and Elad Gil interview Roblox CEO Dave Baszucki about the company's "Holodeck" vision. Baszucki details how Roblox uses AI and 13 billion hours of monthly user data to train native models for advanced NPCs and 4D immersive simulations. The discussion covers AI's role in virtual interactions, physics simulation, and the future of human connection.
Roblox is using AI to create realistic virtual worlds where characters act more like people. They train these AI characters using massive amounts of player data to make them smarter and more engaging for everyone playing.
This episode offers insight into how a major gaming platform is integrating advanced AI beyond LLMs. It's for developers and business leaders interested in AI's application in immersive environments and user data utilization. Roblox's approach to training native AI models for realistic NPC behavior and complex simulations aligns with current frontier lab efforts in multimodal AI and agentic systems, aiming for more intuitive and engaging virtual experiences.

From “virtual doppelgängers” to “real-time dreaming,” online gaming platform Roblox is using AI technology to build the “Holodeck” envisioned in science fiction decades ago. Sarah Guo and Elad Gil sit down with Roblox CEO Dave Baszucki at Roblox headquarters to explore the intersection of AI, physics simulation, and the future of human connection. Dave discusses the evolution of the 4D creation tool in Roblox, a high-fidelity simulation that enables thousands of people to interact in real-time with photo-realistic graphics and acoustic physics. Dave reveals how Roblox is leveraging 13 billion hours of monthly user data to train native AI models that go beyond simple LLMs, enabling NPCs that can navigate and play games with human-like intuition. He also talks about how immersive communication will change video conferencing, how Roblox searches for unlikely talent outside of traditional elite universities, and how he balances rapid weekly iterations with keeping a “long view” on Roblox’s vision.
